PADDING.

Application filed October 25, 1923. `Serial No. 670,717.

To all whom t may concern:

Beit known that I, ALLISTER S. MITCH- ELL, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Padding, of which the following is a specification.

My invention is an improved padding primarily designed for padding the upholstery of an automobile. This application is a continuation in part of my copending application #564,705, filed May 31, 1922.

The padding now used in the upholstery of automobiles consists of a fibrous material placed beneath the outer cover of the seat. The fibrous material has in the past .been inserted by various means such as by sizing the material on both sides, drying the same, cutting the material into proper lengths, folding to the proper width, and then insertin the same beneath the covers of the seat. his entails considerable waste of material and labor.

My padding is formed complete in one operation and is made into a substantially tubular form of many yards in length, so that the same may be inserted into a proper instrument, the instrument inserted into the pleats of the seat, lthe instrument being then withdrawn, the padding sliding through the instrument and the paddin bein then cut or torn to the proper lengt so that practically nol material is wasted.

In order to increase the tensile strength of the paddin I find it advisable to reinforce the pad ing by 'means of a strip of relatively strong paper. The paper furthermore serves as a means for holding the paddin in proper form, which form is prefera ly tubular. v

One ofthe objects of having the padding in tubular form is to increase the resiliency thereof, and to more readily' conformv it to irregularities in the shape of the pleat.

Other objects and advantages of this invention Will appear upon a reading. of the following description.

Referring to the annexed drawing, in: 5o which my invention is illustrated and which forms a part of this specication:

Figure 1 is a perspective view of my improved padding, and

Figs. 2-11 inclusive are diagrammatic end4 views of various modifications of my-inven tion.

In each of these views, a sheet of soft fibrous material 1 such as cotton or lint is folded into substantially tubular form, as illustrated.

In Figs. 4 and. 5,`the material is folded substantially in the shape of the letter O.

In Figs. 6, 7 and 8, the ends 2 and 3` are turned under.

In Figs. 9, 10 and 11, a double fold is formed by brin ing the ends 4 and 5 substantially toget er and then folding the parts 6' and 7, as indicated, thereby makin a double fold.

n any case, the material Vis rolled into substantially a tubular form and is held in that position by means of a strip of paper 8 or other material, whereby tensile strength ma be added to the padding.

he strip 8 may be placed either on the inside or outside of the padding. In Figs. 4, 7 and 10, it is shown as bein placed on the outside of the padding. n these figures, the stri 8 is provided with glue or other adhesive 10, on its underside, which serves as a means to hold the padding in its folded or tubular form;

In Figs. 5, 6, 8, 9 and 11, the adhesive strip 8 is glued on its upper side, thereby holding the material in its folded or tubular form. In Figs. 8 and. 9, the strip 8 is folded on itself, as at 11, and an adhesive 12 holdsthe strip in the folded position substantially as shown. v

In Figs. 1, 2 and 3, the strip 8 is provided with an adhesive on both of its sides.

In the specification and claims where I have used the word tubular, as describing the shape of the finished article, I do not mean that the article is perfectly round or that there is at alltimes a space between the adjacent layers of the folded article. In using the Words tubular form, I means that the lower layer of the padding is not held rigidly against the upper layer, or layers, which structure is shown in each of the figures of the drawings.

While'I have shown several specific forms of my invention, it is obvious that many variations might be made without/departing from the spirit of this invention. I,

esk

therefore, do not limit myself to the par-l ticular form shown except as ll might limit myself` in the annexed claims.

l claim: 1. A padding comprising a sheet of soft material and a strip of relatively strong material, said strong material being provided with an adhesive on one side only thereby uniting the strong material to the soft material, the folded edges of said soft ma terial being thereby held together so as to form substantially a tube. v

2. A padding comprising a sheet of soft material and a strip of material having an adhesive on one side only, said soft material enclosing said strip, said strip of material serving as a means to add tensile strength to the padding.

3. A padding comprising a sheet of librous material folded into substantially tubular form and a strip of paper having a less Width than the Width of the folded material and having an adhesive on one side only, said paper strip serving as a means' Memisa to hold the fibrous material in its substantially tubular form.

4. A padding comprising a sheet of fibrous material folded upon itself and an adhesive strip enclosed Within the fibrous material and adapted to retain said material in its folded form.

5. A padding comprising a sheet of resilient material having a plurality of folds and an adhesive strip whereby said material is held in its folded form said strip being enclosed by the resilient material. Y

6. A padding comprising a folded shee of soft material and a strip of relatively strong material, said strong material ex tending through the length of the soft material and being of less Width than the folded sheet, said strong material being provided with an adhesive on one side only,

`Wl1ereby the edges of said soft material are held together so asv to form substantially a tub ln testimony whereof l afiix my signature.
